The invention relates to an axle-mounted brake disk for a rail vehicle, comprising two friction rings which are arranged in parallel and at a distance from each other and are interconnected by a plurality of ribs extending in the direction of the rotational axis of the friction rings, where at least some of the ribs are embodied with different cross-sections from each other, where the cross-sections of a first subset of the ribs, embodied as supporting elements transmitting pressure forces, do not fall below a minimum cross-section, defined by the stability required in relation to the mechanical load during a brake process, and the cross-section of a second subset of the ribs, used to radiate thermal energy, falls below the minimum cross-section.

A slack adjuster for use with a braking system which has an increased let-out length that enables the use of brake shoes having an increased thickness. The slack adjuster includes a dual spring and canister assembly, an external yoke trigger, or a combination of both the dual spring and canister assembly and the external yoke trigger. A method of retrofitting a truck-mounted brake system is provided, in which the slack adjuster is positioned within the brake system in order to increase the let-out length while maintaining a predetermined spatial envelope within the brake system. The slack adjuster has an increased let-out length enabling the use of thicker brake shoes without requiring modification of the interacting components of the truck mounted brake system since the overall size of the slack adjuster remains the same.

A wheel carrier assembly for a front axle or rear axle of a motor vehicle, with a wheel carrier part on which a link for a control arm assembly, a fixing device for a damper strut and a recess for a wheel bearing are provided. The wheel carrier part includes an air guide device for supplying air to a disk brake assembly, which as brake parts has at least a brake disk and a brake caliper. The wheel carrier part has a circumferentially hollow wheel carrier housing part. The air guide device includes at least one air inlet opening and at least one air outlet opening directed onto a brake part.

A braking band extends between an inner diameter and an outer diameter. The braking band has two plates having inner surfaces delimiting a gap, outer surfaces having opposite flat circumferential portions and a plate body having an extension in axial direction. The plates are joined by connecting elements. At least one plate has at least one projection projecting into the gap without reaching the opposite plate, forming a localized narrowing of the gap and a thickening of the plate body, creating a localized increase of the thickness of plate. The projection extends from a first connecting element to an adjacent connecting element, connecting them, and along the circumferential direction, connecting at least two adjacent connecting elements. A group of projections extends circumferentially along a discontinuous annular path, avoiding a uniform distribution in circumferential direction.

A system, and associated method, for reducing oxidation of a friction disk may include a braking assembly comprising the friction disk and a conduit coupled to the braking assembly, with the conduit being in selectable fluid providing communication with the braking assembly. That is, the conduit may be configured to deliver inert fluid to the braking assembly, thus reducing the concentration of oxygen in the vicinity of the friction disks and thus reducing/mitigating oxidation of the friction disks.

Apparatuses, systems, and methods apply, with a fan, a braking force to a vehicle that includes an axle. The fan is rotated at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed. The first rotational speed is different from the second rotational speed. The fan applies the braking force when the fan rotates at the first rotational speed.

A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.
